In standard market theory demand and cost functions have to be known to compute optimal price or quantity responses. In case of risk or uncertainty the decisions depend on expectations, i.e. estimated parameters. Even in case of rational inference these expectations itself are uncertain, at...

This paper analyses the effects of innovation networks on product and process innovation and sales growth of high technology SMEs. Innovation net- works are positively related to both product and process innovation, i.e. knowledge creation. One exception is the negative effect of innovation...

We experimentally investigate competition in innovation in a patent race scenario. Pairs of subjects compete as seller firms on a duopoly market, engaging in risky search investments. Successful innovation is rewarded through temporary monopoly rents. Throughout the interaction, subjects receive...

In an experimental setting, firms in a duopoly market engage in a patent tournament and compete for profit-enhancing product advancements. The firms generate income by matching exogenously defined demand preferences with an appropriately composed product portfolio of their own. Demand...

Innovative start-ups are an important driver of economic growth. This article presents empirical evidence on the effects of R&D on new product development, inter-firm alliances and employment growth during the early life course of firms. We use a dataset that contains a sample of new firms that...

This paper discusses the determinants of product innovation in young innovative companies (YICs) by looking at in-house and external R&D and at the acquisition of external technology in embodied and disembodied components. These input-output relationships are tested on a sample of innovative...

Das Papier charakterisiert die spezifischen Eigenschaften des Gutes Software. Als Alternative zur Bereitstellung von Software über Märkte werden die Charakteristika der "freien" Open-Source-Softwareentwicklung dargestellt, bei der die Entwickler auf eine unmittelbare kommerzielle Verwertung...

In case of digital goods such like music, intellectual property rights are typically not exerted by the creators (artists) but by intermediaries. Their profits, and therefore also the income of the artists, are endangered by copyright infringements (piracy). It is well known from static welfare...

Structural vector-autoregressive models are potentially very useful tools for guiding both macro- and microeconomic policy. In this paper, we present a recently developed method for exploiting non-Gaussianity in the data for estimating such models, with the aim of capturing the causal structure...

Transparency in teams can induce cooperation. We study contribution decisions by agents when previous decisions can be observed. We find that an information chain, in which each agent directly observes only the decision of her immediate predecessor, is at least as effective as a...
